eli5: How does depth perception work?

Question

I don’t naturally have it so visual explains don’t make sense to me

Answer 1

Two images from very slightly different angles gives the brain enough information to gauge depth a little

You mentioned visual explanations aren’t very helpful for you, but, here is one anyway

If you look at a cube straight on, with no depth perception, it appears to just be a square (one side). If you look at it from slightly to the left, you can see some of the left side. Same if you look from slightly to the right. If you combine both of these images, you actually see a little of the left and a little of the right at the same time, allowing the brain to form a better idea of the actual shape (a cube).
